Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a memory located inside the data processing device is used, then the performance of data processing is improved, but there are limitations in increasing the capacity of the memory

Engineering Contradiction:

Improvedata processing performanceVSAvoidmemory capacity

Core Design Contradiction:

SpeedVSQuantity of substance

Solution Approach 1:

The patent combines internal memory and external memory into a unified memory system that operates together. The processing unit can access both internal memory (for high-speed operations) and external memory (for large capacity storage), merging their advantages to simultaneously achieve high performance and large capacity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The memory system is designed to serve multiple functions: the internal memory provides fast access for active processing, while the external memory provides expanded storage capacity. The system can dynamically allocate data between these two memory types based on access frequency and size requirements, making the memory subsystem universally adaptable to different performance and capacity needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Quantity of substance

If an external memory is used to increase capacity, then the memory capacity is increased, but the performance of data processing may be reduced due to communication delays

Engineering Contradiction:

Improvememory capacityVSAvoidcommunication delay

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The memory system is segmented into internal memory and external memory components. Frequently accessed data is kept in the internal memory close to the processing unit for fast access, while less frequently accessed data is stored in the external memory. This segmentation minimizes communication delays by ensuring that time-critical data operations occur in the internal memory while capacity-intensive operations use the external memory.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary memory controller that manages data transfer between the processing unit, internal memory, and external memory. This intermediary optimizes access patterns by caching frequently accessed data in the internal memory and managing data movement between memory levels, thereby reducing the effective communication delay when accessing external memory while maintaining the benefits of increased capacity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An input/output unit communicates with a memory located outside a data processing device to provide a sub-processing function to perform data processing using a memory located inside the data processing device and a memory located outside the data processing device. Delay due to access to the memory located outside the data processing device by a processing unit of the data processing device may be reduced, and processing performance by the data processing device may be improved.
